Previous short-read based nascent RNA sequencing methods, such as pNET-seq, plaNET-seq, and GRO-seq have been applied in Arabidopsis [39–42] and in other plants including cassava and maize , are mostly developed for detecting Pol II-associated elongating RNAs, and can also detect RNA signal downstream of poly(A) site. et al. Data Sources. 1101/844522 EID: 2-s2. , intronic circular RNAs) in Arabidopsis by utilizing the RNA-sequencing data. Arabidopsis RNA-Seq Database. Plants were grown for 5 d in liquid MS medium. In addition, we. 1. Our previous Arabidopsis RNA-seq database (ARS) has been updated recently, and the number of libraries has been increased from 20 068 to 28 164 (Zhang et al. Lastly, the eFP-Seq Browser tool (BAR) permits the visualization of 113 RNA-seq data sets used to create the ARAPORT 11 reannotation of the Arabidopsis genome (Cheng et al. applied a plate-based scRNA-seq method, Switch Mechanism at the 5′ End of RNA Templates (Smart-seq), to profile 19 Arabidopsis root phloem cells. 5 million reads were uniquely mapped to the Arabidopsis. In the central cell of tetraploid plants, DEMETER (DME) is upregulated, which. 2. Bioinformatic analysis of the deep sequencing data indicated that RSV infection triggered the generation of relatively large amounts of vsiRNA, accounting for 1. 4) to frozen, ground material. 3: PIF7 directly activates the warm temperature transcriptome in response to daytime thermal cycles. Recent crystallization of the DBD of two Arabidopsis ARFs revealed a dimerization domain within the DBD that. However, the comprehensive transcriptional framework of DNRR remains elusive. (C and D) Pairwise correlation plots of the RNA-seq profiles generated from isolated VN. performed ChIP–seq and RNA-seq experiments. In addition to the RNA-Seq reads obtained from the NCBI database, we will use datasets from two sources: AtRTD2 is a high-quality transcript reference dataset developed to exploit the accuracy of transcript quantification tools such as Salmon and Kallisto in analyzing Arabidopsis RNA-Seq data. , 2005a ). The RNA-seq data of 40 samples from leaf and silique tissues of multi genotypes of Arabidopsis in the present study were from our previous study, including the overexpression of AtLEA, AtVOC, RNAi of AtVOC, and AtLEA mutant (Liang et al. e. Plant 13, 1231–1233 (2020). rapa, C. thaliana Tair10 genome assembly using STAR2 58 with default parameters. RNA-seq and expression data demonstrated that the transcript of ABA-responsive genes HAI1 and AIP1, members of PP2C. After. The expression levels were calculated in fragments per kilo base per million mapped reads (FPKM) from three. Illumina sequencing of chromatin-associated RNA has been used to study CTS in Arabidopsis [18, 19] and soybean [17]. 0-85095656022.
